Impedance matching

Introduced: January 2011

Full Title

Full titles differ between systems:

IPC:

Details of coupling devices of the kinds covered by groups or > specially adapted for high-frequency, e.g. structures providing an impedance match or phase match > Impedance matching

CPC:

Details of coupling devices of the kinds covered by groups H01R12/70 or H01R24/00 - H01R33/00 > specially adapted for high-frequency, e.g. structures providing an impedance match or phase match (non-coaxed protective earth or shield arrangements H01R13/648; coaxed connectors specially adapted for high frequency H01R24/40) > Impedance matching

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2011.
